Power Assist Check

Power Assist Check

NOTE: This test should be done with original equipment tires and wheels at the correct tire pressure.

1. Hydraulic power steering type: Check the power steering fluid level.

2. Start the engine, let it idle, and turn the steering wheel from lock to lock several times to warm up the component and the fluid (hydraulic power steering type).

3. Attach a commercially available spring scale (A) to the steering wheel. With the engine idling and the vehicle on a clean, dry floor, pull the scale as shown, and read it as soon as the tires begin to turn.
- If the scale reads no more than the specification, the steering gearbox and pump (hydraulic power steering type) are OK.

- Hydraulic power steering type: If the scale reads more than the specification, troubleshoot the steering system.

- EPS type: If the scale reads more than specification, check the steering linkage, Steering Linkage and Gearbox Inspection and check the rack guide adjustment. Adjustments
